The descendants, therefore, of Adah, and what she herself is, have now been explained. Let us consider next the other wife of Lamech, Zillah, and what she brings forth. Zillah, then, being interpreted, means "shadow," a symbol of the qualities of the body and of the external good things, which, in their real essence, are in no way better than a shadow. Is not beauty a shadow, which, after it has flourished for a brief time, withers away? And are not strength and activity of body shadows, which any chance disease can destroy? And the organs of the external senses, and the accuracy of their use, which any sudden cold may obstruct, or old age, that inevitable and common disease of all men, may impair, are not they shadows? And, again, are not riches and glory, and authority and honours, and all the external circumstances which are accounted goods, are not they, I say, all shadows?
